And the upper part of said ii) and iii) is positioned so as not to disturb the heat transfer from the reactant to said i) (or vice versa) in use. Preferably, the upper parts of ii) and iii) are interposed between i) and the outer surface of the container.

  According to one aspect of the present invention, there is provided a container suitable for containing at least one product (eg, a food product) to be heated or cooled, the container being a food product or other An integrated and activatable heating (or cooling) system for the product of the product, and a lining, the lining and the container providing at least three mutually isolated areas, i. Or one or more areas that contain other products; ii) areas that contain the first type of chemical reactant; iii) areas that contain the second type of chemical reactant. Is defined. The container further comprises a rotatable activator (eg, an activation knob located outside the container) and an isolation of the above ii) and iii) that is rotatably mounted within the container and operated by rotation of the activator. And ii) and iii) are provided with a hole (preferably pre-formed) closed by a movable member, and ii) and iii) A means for terminating the separation moves the movable member by realignment, for example, and mixes two kinds of reactants by activation, thereby heating or cooling i). Preferably, the hole opening means comprises a manifold that is in fluid communication with the ii) and iii) simultaneously, and can be aligned with the hole by rotation of the activator.

  There is no restriction | limiting in particular about the shape of the said container, For example, a square shape, circular shape, or an oval shape may be sufficient. This container (or outer bowl in the case of a general circular shape) is preferably made of plastic material, preferably by injection molding. The bowl may be relatively wide, such as a typical soup bowl, or a relatively narrow mouth such as a soup or coffee cup. Desirably, the thickness of the container does not exceed 1.0 mm, more preferably in the range of 0.3 to 0.7 mm. However, it is beneficial to increase the thickness locally. The lining (or inner bowl in the case of a general circular shape) is made of plastic material and can be manufactured by thermoforming or injection molding, but by using metal foil such as aluminum foil or tin foil, You may shape | mold into a desired shape. The metal is preferably coated with a plastic material to facilitate spot welding or splicing to the throat (constricted passage) of the container. The metal may be further coated with a lacquer or plastic material on the part that contacts the foodstuff.

  As a preferred embodiment of the container, the regions ii) and iii) are injection-molded as an integral structure. In this embodiment, the lining includes i).

  In a preferred embodiment of this container, at least one of said regions ii) and iii), preferably both, is filled with reactants before the lining is joined to the inside of the container, for example by spot welding. In fact, as a further aspect of the present invention there is provided a partial container having no lining, having said regions ii) and iii), at least one of which is preferably filled with reactants. The

  The rotatable activator can be gripped by the user. This may be in the form of a knob, lever, handle, key or switch, for example. The activator and the means for terminating the ii) and iii) interlocking with the activator can also be appropriately injection-molded as an integral structure. This structure is preferably mounted by pressing and inserting into a predetermined position in the container at a low temperature while heating the container to a high temperature.

  The area in which the liquid chemical reactant is accommodated is in use above both the area in which other types of chemical reactants are accommodated and the means for terminating the isolation of said ii) and iii). It is preferable that it exists in. Furthermore, the iii) is preferably located below the i). It is preferred that the first type of chemical reactant is present as a liquid, which in use is fed into the region iii) by gravity.

  When mixed, the two types of chemical reactants can produce a heat or cooling action. An example of the former is a system in which the first type of chemical reactant includes fuel and the second type of chemical reactant includes oxidant. For example, where the fuel includes a glycol such as glycerol, the oxidant includes permanganate. Another class of systems that generate heat is one in which one of the chemical reactants solvates or hydrolyzes the other, creating an exotherm. In one example, one type of reactant is calcium oxide and the other type is water. An example of the latter system that produces a cooling effect is one in which one of the chemical reactants solvates the other, but produces a cooling effect. In one example, one type of reactant is ammonium nitrate and the other type is water. At least one of the chemical reactants may include a diluent.

  While not intending to limit the universality of the present invention, it further includes a first type of chemical reactant comprising glycerol, along with a second type of chemical reactant comprising potassium permanganate. explain. The glycerol may be present as an aqueous solution. The permanganate may also be present as a solution such as an aqueous sodium permanganate solution or as a solid such as potassium permanganate. This latter solid is described, for example, in US Pat. No. 5,035,230 (Patent Document 2) and US Pat. As disclosed in US Pat. No. 5,984,953 (Patent Document 3), it is preferably embedded in a soluble binder. A preferred oxidant is an alkali metal permanganate. If this second type of chemical reactant is a solid, it may be present in the lower part of the container as a rose, or in a bag or by application.

  In certain embodiments utilizing a potassium permanganate oxidant, it may be desirable to add a reaction moderator in the heat recipe. One example is a non-fuel gelling agent, for example, see US Pat. 6, 116, 231 (Patent Document 4) (issued on September 12, 2000). In an embodiment in which the reagent used for the exothermic reaction generates a rapid exotherm due to the rapid temperature rise of the product to be heated, a salt such as borax or sodium borate for mitigating or capping the temperature rise It may be desirable to add. An example is disclosed in, for example, US Patent PCT / US2005 / 015793 (Patent Document 5), which is a pending patent application. The capping reagent can be incorporated into the fusible wax, which is thermally bonded to the product container and released when the product container reaches a selected temperature.

  In a particularly preferred embodiment of the invention, region ii) may contain an aqueous glycerol solution, which may further comprise an anti-foaming agent. A part (preferably the upper surface) of a lower region of this region is formed as a hollow cylinder having a hole, and enables communication between the region ii) and the region iii) when opened. The means for terminating the isolation of said areas ii) and iii) has a barrel. This barrel has a hole or slot and is adapted to fit in the cylinder in a liquid-tight manner. This means is attached to the activation knob. In the inactivated state, this hole or slot is preferably provided in a radial direction opposite to the hole of the cylinder. As a result, these areas are isolated.

  In another preferred embodiment of the invention, region ii) is formed as a circumferential reservoir on region iii). Said hollow cylinder has two holes (preferably on its upper surface), one of which allows communication between the lower part of region ii) and region iii) when open, the other one One allows communication between region iii) and the space above region ii) via a conduit when opened. The means for terminating the isolation of the regions ii) and iii) have a barrel, which is constructed as two manifolds that fit in a liquid-tight manner into the cylinder. This means is attached to the activation knob. In the unactivated state, these manifolds block both holes, thereby leaving these regions isolated.

,
This activation knob preferably has a misuse prevention means (means devised so as to reveal a tampering or tampering trace) in order to prevent unintended activation. The first misuse prevention means includes a brittle member for preventing rotation of the activator, for example, a brittle connection member between the knob's upright handle or tab and the knob's boss. In order to activate the container, the fragile connecting member must be broken by pulling down the tab. The breaking action of this brittle member provides evidence of tamping. It is preferable that the container further has second misuse prevention means effective to prevent reverse rotation of the knob that is at least partially rotated. This second misuse prevention means may comprise a claw-pull wheel system operated in conjunction with the means for terminating the isolation of areas ii) and iii). In addition, at least a part of the front end of the slot may be formed as an elastic tooth that is introduced into the hole when activated and prevents reverse rotation. In a further embodiment of the second misuse-preventing means, the activator is initially prevented from rotating, and the portion of the brittle member that remains on the knob boss upon activation prevents reverse rotation. It interacts with the interference member. Preferably, this second misuse prevention means should be immediately operable when in use when the hole begins to open.

  Preferably, a third misuse prevention means is provided once all three areas of the container are filled and sealed. Even when the knob or other activator is rotated, the seal is removed from the breathable cover for area ii) and the liquid chemical reactant is discharged through the hole into area iii) by gravity supply. Until done, this system will not function properly, and in some cases, probably will not function at all. The vent is preferably countersunk. Early activation without removal of the seal at least mitigates the generation of heat, thereby providing safety measures. Removal of the seal from the vent of the cover for region ii) will also provide misuse prevention means. In some cases, it is desirable to provide pressure balancing means between the upper parts of regions ii) and iii). For example, gas permeable, liquid impervious ports, conduits or notches are provided between the upper parts of regions ii) and iii) to prevent stagnation of the thermal insulation layer of air directly under region i). In particular, it can be done in communication with the vent in region ii) as described above. The port can be closed with a pressure stopper, but the discharge pressure is very low, for example 2 psig, so as not to pressurize the container.

  The container may further include a plurality of reinforcing ribs spaced apart from each other at the periphery. These ribs can also be held by hand and provide a certain degree of thermal insulation to the consumer. Similarly, a recess may be provided at the bottom of the container to avoid heat transfer to the support surface. In some cases, it is also appropriate to provide insulation in the lower region of the container to provide both consumer comfort and the thermal efficiency of the heating system. The heat insulator may be made of, for example, cardboard, foam, or CPET sleeve.

  The container and / or lining can be made from a filled or unfilled plastic material with a pour point higher than 110 ° C, preferably higher than 135 ° C. Retort sterilization is performed at temperatures up to 125 ° C. Therefore, the lining must be able to withstand at least this retort sterilization. Preferably, the container and / or lining is made from a plastic material including, for example, a polyolefin such as polypropylene, PET, or polyester. If desired, the lining may include a continuous barrier layer such as EVOH. It is particularly preferred that the lining is thermoformed from polypropylene and the container is injection molded from polypropylene.

  According to a preferred feature of the present invention, the activation knob and the misuse tab can be configured to function as a traditional gas cooker knob to promote consumer confidence, the tab being in use Is pulled down (and thereby breaking the fragile misuse prevention means), locked into a groove in the knob, and then used to rotate the knob.

  According to another preferred feature of the invention, it includes an external thermochromic region that is in thermal contact with region i), which has the effect of changing color upon heating. This area may be provided on the knob (eg shown as a spot in the center of the knob), or this area may be represented on the foil cover, or this area may be an area for promotional display, there The thermochromic region may appear as a display.

  As a further aspect of the present invention, a filled container is provided wherein region i) contains a food product. If the food product to be stored in region i) is a stable food product, the food product may be stored in region i) before being incorporated into the container. However, in general, the containers have regions ii) and iii), which contain chemical reactants, the substructure is lined, a vent is formed in the lining, the lining is filled, The container is sealed.

  The filled container is sealed, and this sealing portion may act as a third misuse prevention means. The sealing portion may be made of paper, card, plastic foil or metal foil. The filled container may further include a push-fit plastic lid and / or housed in a card sleeve where the seal is a hermetic seal and the food product is sterilized as needed.

  According to a further aspect of the present invention, there is provided a method for the manufacture of a filled container according to the present invention, which comprises the first and second types of chemical reactants in regions ii) and iii). Respectively including: a step of adhering a lining to the container; a step of forming a vent in the lining on region ii); a step of filling region i); and a step of sealing the container . Preferably, region i) is filled before the step of adhering the lining to the container.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to FIGS. 1-9, these show a first embodiment of a container (101) such as a bowl, for example, which is made in a generally circular shape using polypropylene, preferably by injection molding. . The container opening is formed as a lip (102) from which a plurality of spaced apart integral reinforcing ribs (103) are formed downwardly. The container is formed with a substantially tapered depth, and the lower part thereof is constricted to form a base (104). An indication (105) is marked between two adjacent ribs (103A, 103B), and a housing (106) for an activation knob (107) is formed between the lower areas of these ribs. ing. An integral flange (108) is formed on the lower arcuate peripheral surface of the knob, and this flange extends upward to a misuse prevention tab (109) that covers the display. A strip of thin (110) is formed in the diameter of the portion of the flange that extends to the tab, and the tab is separated from the knob around the upper semicircle of the knob, except for the brittle joint (111). Has been. The knob (107) is provided with a pair of grooves (112, 112 ′) spaced along the radial direction passing through the thin portion (110), and when the fragile joint (111) is broken during use, The tab is received in an indentation style. The portion of the weak joint (111A) left on the knob is rotatable to get over the chamfered pin (112B) provided integrally with the container in use so as to prevent the knob from reversing. It has become. The inner or outer bowl (113) of the container has two regions by means of an integral partition (114), a convex region (115) in which a second type of chemical reactant is accommodated, and a second number of chemical reactants. It is separated into a crescent-shaped region (116) in which one kind of thing is accommodated.

Yes. The flange (208) extends upward toward the misuse prevention tab (209). The tab (209) is separated from the boss except for the weak connection (211). A thin band is formed in the diameter portion of the portion where the flange extends to the tab, and two tongue rows (210) and groove rows (210 ′) are provided as boundaries, which are used in use. When the fragile connection (211) is broken, it is aligned to receive the tab in an indentation manner. The body (206) is provided with a circumferential ratchet wheel (250) (partially shown), which engages the claw (251) provided integrally with the boss (204). This prevents accidental reversal of the knob. The housing (206) further includes two lugs (264, 264 ′) on opposite sides in the radial direction along the lines of the two rows (210, 210 ′) in the unemployed position. ) To prevent accidental reversal of knob (207) as tab (209).

  The container (201) has a lip (252) on which a coaxial flanged lining (220) made of polypropylene-coated metal with a throat (253) with a recess is placed and spot welded and spliced together. Yes. This lining is incorporated into the upper wall surface of the container (201) and is pressed into the inner wall surface of the first storage part (216) arranged in the circumferential direction. The first reservoir (216) can accommodate a first type of reactant, such as an aqueous glycerol solution. A second storage part (215) is provided below the lining so as to be integrated with the container. The second reservoir (215) can accommodate a second type of reactant such as permanganate.

  Two vent holes (254, 255) communicating with the storage unit are provided in the upper part of the outer wall surface of the first storage unit (216). The upper vent (254) releases steam (when generated by the reactants) and is covered with a filter material (not shown). The lower vent (255) is for failsafe pressure release and is covered with adhesive tape (not shown). Both vents lead to absorbent-filled cotton (257) housed in a substantially trapezoidal depression (258) on the container wall surface via a substantially triangular trough (256) provided on the outer wall surface of the container. .

  A portion of the base of the first reservoir (216) is formed as an integral generally cylindrical housing (217), which is in coaxial communication with the housing (206). Further, the housing is orthogonal to the container axis, and a horizontal hole (218) is provided at the top of the housing (217). The first reservoir is further provided with a conduit (259) having a convex wall surface, which is the first reservoir (216) near the upper region of the housing (217) and the upper vent (254). ) Communicate with the upper area. The activation knob (207) is integrally formed with the mandrel (221), and the mandrel (221) is press-fitted in a liquid tight manner in the housing (217) held by the flange (261). The inside of the mandrel is formed as two manifolds (262, 263), and the lower manifold (262), when in use, connects the first reservoir (216) to the second reservoir (through the hole (218). 215), and the upper manifold (263) simultaneously communicates the conduit (259) with the second reservoir (215). However, in an unoperated state, both manifolds (262, 263) are not aligned with the first reservoir (216) and conduit (259), respectively.

  The reactant (not shown) can be accommodated in the reservoir before the lining is indented into place and spliced by spot welding.

  After the foodstuff (not shown) is then housed in the lining, the container is sealed across the recessed throat (253) with foil (not shown) and then sterilized.

  In use, the consumer removes the sealing foil (not shown) and manipulates the tab (209) downward to break the fragile joint (211); position it in the groove row (210 ′); Rotate clockwise. Thereby, the mandrel (221) rotates, and the hole (218) communicates with the second reservoir (215) via the manifold (262). As a result, the liquid first type of reactant in the first reservoir (216) flows out by gravity and mixes with the second type of reactant to generate heat (or endotherm). The lining (220) and its contents will be heated (or cooled). At the same time, the manifold (263) will be in communication with the conduit (259) so that the air on the second reservoir (215) will flow into the first reservoir (216) and the vent (254). Thus, smooth and controlled mixing of the reactants can be ensured. If the reactants generate heat, the vapor generated in the second reservoir (215) can be passed through the trough (256) to the absorbent cotton (257).
